Sprinter Transmission Fluid Change Interval Information
What is the Sprinter transmission fluid (ATF) change interval?
We recommended changing your Sprinter transmission fluid and filter every 80,000 miles or 8 years whichever occurs first.
Sprinter vans that experience more aggressive driving styles, used in the commercial delivery industry, contractor trade industry, constant extreme heat, heavy city traffic, trailer pulling, Sprinter RV conversions or other severe driving conditions should consider replace the transmission fluid and filter more frequently such as every 40,000 - 50,000 miles.

It is best to use the MB recommended transmission fluid. In N. America that would be MB236.12 or MB236.14 spec fluid. The MB236.10 fluid is an older spec and is no longer easily found. MB236.12 and MB236.14 are fully backward compatible to the MB236.10 spec.
Any MB236.14 brand listed on this BeVo page is a good choice.

Many Sprinter owners have had good results using Valvoline MaxLife Multi-Vehicle Full Synthetic Automatic Transmission Fluid. The Valvoline ATF is readily available on the shelves in the US. (Check the price at Walmart.) That said, the easiest choices, but not the cheapest, are found in the MB236.14 BeVo list.
